A torque tube sensor (150) to measure torque on a torque tube (105) or shaft includes: a sensor body including at least a first body section (152) and a second body section (154); one or more strain gauges including a first strain gauge disposed in the first body section; at least one transmitter (210); and strain gauge circuitry (700) connected to the first strain gauge (202a) and at least three other resistive elements in a Wheatstone bridge configuration including two arms (Al, A2), the transmitter being connected between the two arms. The sensor also includes at least one receiver (212) configured to receive signals generated by the at least one transmitter; and an armature carried by the first body section that interacts with a permanent magnet stator (220), the armature being in electrical contact with the strain gauge circuitry and providing power to the strain gauge circuitry and the receiver. The sensor can be part of an assembly.
